Debt Disclosure [Abstract] |
Convertible Notes Payable | Convertible Notes Payable In December 2006 and January 2007, the Company issued a total of $115.0 million of convertible notes with a fixed interest rate of 3.75% due 2026 (the “Convertible Notes”). The Convertible Notes were issued at par and require interest payments semi-annually in arrears on June 15 and December 15 of each year. The Convertible Notes are unsecured unsubordinated obligations and rank equally with all other unsecured and unsubordinated indebtedness. The Convertible Notes have an effective interest rate of 6.03% giving effect to the accounting treatment required by ASC Topic 470-20, “Debt with Conversion and Other Options.” The Convertible Notes had an initial conversion price of $30.86 per share. The conversion rate may be adjusted under certain circumstances, including the payment of cash dividends in excess of the regular quarterly cash dividend in place at the time the Convertible Notes were issued. As of December 31, 2011, the adjusted conversion price is $29.26. Upon conversion of the Convertible Notes, the Company will deliver cash and, in some circumstances, Common Shares, as specified in the indenture relating to the Convertible Notes. In general, the Convertible Notes may only be converted prior to maturity during any calendar quarter beginning after December 31, 2006 if the Company’s Common Shares trade at 130% of the conversion price for at least 20 days within a consecutive 30 day trading period. Prior to December 20, 2011, the Company did not have the right to redeem Convertible Notes, except to preserve its status as a REIT. After December 20, 2011, the Company has the right to redeem the notes, in whole or in part, at any time and from time to time, for cash equal to 100% of the principal amount of the notes plus any accrued and unpaid interest to, but not including, the redemption date. The Holders of notes may require the Company to repurchase their notes, in whole or in part, on December 20, 2011, December 15, 2016, and December 15, 2021 for cash equal to 100% of the principal amount of the notes to be repurchased plus any accrued and unpaid interest to, but not including, the repurchase date (the "Repurchase Option"). In general, upon a conversion of notes, the Company will deliver cash and, at the Company’s election, its Common Shares, with an aggregate value, which the Company refers to as the “conversion value”, equal to the conversion rate multiplied by the average price of the Company’s Common Shares. The net amount may be paid, at the Company’s option, in cash, its Common Shares or a combination of cash and its Common Shares. The Convertible Notes "if-converted" value does not exceed their principal amount as of December 31, 2011 and there are no derivative transactions that were entered into in connection with the issuance of the Convertible Notes. Effective January 1, 2009, the Company adopted ASC Topic 470-20 which required it to retrospectively restate and reclassify previously disclosed consolidated financial statements to allocate the proceeds from the issuance of convertible debt between a debt component and an equity component. The resulting discount on the debt component was amortized over the period the convertible debt was expected to be outstanding, which was December 11, 2006 to December 20, 2011, as additional non-cash interest expense.The equity component recorded as additional paid-in capital was $11.3 million, which represented the difference between the proceeds from the issuance of the Convertible Notes and the fair value of the liability at the time of issuance. As the Company determined, in connection with the Repurchase Option, that the Convertible Notes matured on December 20, 2011, as of December 31, 2011, all loan costs associated with the issuance have been expensed and there is no remaining carrying amount of the equity component included in additional paid-in capital. The carrying amount of the equity component included in additional paid-in capital totaled $1.1 million at December 31, 2010. Interest expense relating to the contractual interest coupon recognized in the Consolidated Statements of Income was $1.5 million, $1.9 million and $2.5 million for the years ended December 31, 2011, 2010, and 2009, respectively, The additional non-cash interest expense recognized in the Consolidated Statements of Income was $0.8 million, $1.0 million and $1.3 million for the years ended December 31, 2011, 2010, and 2009, respectively. During 2011, the Company purchased $48.8 million of the Convertible Notes, including $24.0 million that were repurchased on December 20, 2011 pursuant to the Repurchase Option. As of December 31, 2011, the Company has purchased $114.1 million in principal amount of its convertible debt at an average discount of approximately 11%. The transactions resulted in a (loss) gain on debt extinguishment of ($0.4) million and $7.1 million for the years ended December 31, 2011 and 2009, respectively. The outstanding Convertible Notes principal amount as of December 31, 2011 and 2010 was $0.9 million and $49.8 million, respectively. The outstanding Convertible Notes net carrying amount as of December 31, 2011 and 2010 was $0.9 million and $48.7 million, respectively.
